The Hydraforce 5614935.M28.5 (5614935.M28.5) is a screw-in, cartridge-style, direct-acting spool type hydraulic pressure reducing/relieving valve. This component is designed to regulate pressure in secondary circuits with precision and reliability. It features an internal spring chamber drain and a spool damping chamber to enhance its performance. The valve allows bidirectional flow from port 2 to port 1 in its steady state, with the spring chamber consistently drained at port 3. When a predetermined pressure is reached at port 1, the cartridge shifts to block flow at port 2, effectively regulating the pressure at port 1 and offering relief from port 1 to port 3 at a variable value over the set reducing pressure. Notable features include adjustments that cannot be backed out of the valve, preventing springs from solidifying, and optional spring ranges up to 227.5 bar (3300 psi). The hardened spool and cage contribute to an extended lifespan, while its industry-common size ensures compatibility with various systems. Additionally, there is an option for a protective screen at Port 2 with a rating of 60 mesh and 250 microns for enhanced filtration capabilities.
